Answer:
Ta(Tantalum) has a higher atomic radius than V(vanadium).
Step-by-step explanation:
Ta(Tantalum) has more electrons and energy levels, so its atomic radius is large. Ta(Tantalum) is located further down and left to the periodic table than V(Vanadium) as the atomic radius generally increases down a group from right to left across a period.
Vanadium has an atomic number of 23 and whereas Tantalum has an atomic number of 73.
